problem 2
Fri Apr  2 17:43:17 2021 - SIGPIPE: writing to a closed pipe/socket/fd (probably the client disconnected) on request /cross_server/update_version/ (ip 192.168.10.1) !!!
Fri Apr  2 17:43:17 2021 - uwsgi_response_writev_headers_and_body_do(): Broken pipe [core/writer.c line 306] during POST /cross_server/update_version/ (192.168.10.1)
[ERROR][2021-04-02 17:43:17,212][setup.py:910]An un-handled exception was caught by salt's global exception handler:
OSError: write error
OSError: write error
OSError: write error

Analysis:

The client aborts the connection, and then Nginx closes the connection without telling uwsgi to abort. Then, when uwsgi returns the result, the socket has been closed

Solution

Add parameters to nginx configuration

uwsgi_send_timeout 1800;        # Specifies the timeout for connecting to the backend uWSGI.
uwsgi_connect_timeout 1800; # Specify the timeout for transmitting requests to uWSGI after the completion of the handshake.
uwsgi_read_timeout 1800; # Specify the timeout for receiving uWSGI responses, and the timeout for receiving uWSGI responses after completing the handshake.

uwsgi configuration add parameters
